- A new receiver for the Onsala 20 m antenna with the possibility of being equipped with 3 mm and 4 mm bands has been built and the 3 mm channel has been commissioned during the Spring 2014. For single-dish operation, the receiver uses an innovative on-source/off-source optical switch. In combination with additional optical components and within the same optical layout, the switch provides two calibration loads (for the 3 mm and 4 mm channels), sideband rejection measurement, and tuning possibilities. The optical layout of the receiver employs all cold (4 K) offset elliptical mirrors for both channels, whereas the on-off switch employs flat mirrors only. The 3 mm channel employs a sideband separation (2SB) dual polarization receiver with orthomode transducer (OMT), 4-8 GHz intermediate frequency (IF), x? 2pol x? upper and lower sidebands (USB? +? LSB). The cryostat has four optical windows made of high density polyethylene (HDPE) with anti-reflection corrugations, two for the signal and two for each frequency band cold load. The cryostat uses a two-stage cryocooler produced by Sumitomo HI? RDK? 408D2 with anti-vibration suspension of the cold-head to minimize impact of the vibrations on the receiver stability. The local oscillator (LO) system is based on a Gunn oscillator with aphase lock loop (PLL) and four mechanical tuners for broadband operation, providing independently tunable LO power for each polarization. This paper provides a technical description of the receiver and its technology and could be useful for instrumentation engineers and observers using the Onsala 20 m telescope.

Religious Change in Northern Europe. : The Case of Sweden
- 2004
-
Bok (refereegranskat)abstract
- Detta utgör den sammanfattande raporten från projektet vid Vetenskapsrådet "Från statskyrka till fri folkkyrka". Rapporten visar på den komplexa förändringsbild som gäller Svenska kyrkan inför kyrka stat reformen år 2000 men också religiösa institutioner i stort. Den nordiska religiösa modellen karakteriseras av högt medlemskap och deltagande i riter men med lågt engagemang och gudstro. Detta visar på en individuell integritet i trosfrågor men med samtidigt behov av en kuturell relatering.

- 2011. - 1
-
Bok (refereegranskat)abstract
- This is the second of two volumes emanating from the Welfare and Religion in a European Perspective - project at Uppsala University. It includes four different analysis of the results from a comparative study of eight countries in Europe (Sweden, Finland, Norway, England, France Germany, Italy and Greece), a sociological, gender, theological and general theoretical analysis.

Bok (övrigt vetenskapligt/konstnärligt)abstract
- This is an overview of the relationship between welfare regimes and majority churches in eight selected countries in Europe. It shows that there is a connection between the evolution of the respective welfare regime and the religious organisation prevalent in the country studied. It also shows that a changing role of the welfare state and of religious institutions give religious organisations both an innovative role and a voice in the public debate on solidarity values.

Low-grade intestinal inflammation two decades after pelvic radiotherapy.
- 2023

Tidskriftsartikel (refereegranskat)abstract
- Radiotherapy is effective in the treatment of cancer but also causes damage to non-cancerous tissue. Pelvic radiotherapy may produce chronic and debilitating bowel symptoms, yet the underlying pathophysiology is still undefined. Most notably, although pelvic radiotherapy causes an acute intestinal inflammation there is no consensus on whether the late-phase pathophysiology contains an inflammatory component or not. To address this knowledge gap, we examined the potential presence of a chronic inflammation in mucosal biopsies from irradiated pelvic cancer survivors.We biopsied 24 cancer survivors two to 20 years after pelvic radiotherapy, and four non-irradiated controls. Using tandem mass tag (TMT) mass spectrometry and mRNA sequencing (mRNA-seq), we charted proteomic and transcriptomic profiles of the mucosal tissue previously exposed to a high or a low/no dose of radiation. Changes in the immune cell populations were determined with flow cytometry. The integrity of the protective mucus layers were determined by permeability analysis and 16S rRNA bacterial detection.942 proteins were differentially expressed in mucosa previously exposed to a high radiation dose compared to a low radiation dose. The data suggested a chronic low-grade inflammation with neutrophil activity, which was confirmed by mRNA-seq and flow cytometry and further supported by findings of a weakened mucus barrier with bacterial infiltration.Our results challenge the idea that pelvic radiotherapy causes an acute intestinal inflammation that either heals or turns fibrotic without progression to chronic inflammation. This provides a rationale for exploring novel strategies to mitigate chronic bowel symptoms in pelvic cancer survivors.This study was supported by the King Gustav V Jubilee Clinic Cancer Foundation (CB), The Adlerbertska Research Foundation (CB), The Swedish Cancer Society (GS), The Swedish State under the ALF agreement (GS and CB), Mary von Sydow's foundation (MA and VP).
